Referring to the drawings inv detail, the letter A indicates a door to which is secured a lockconstructed in accordance with our invention. y A

The lock includes inner andV outer escutcheon plates 1 and 2, and formed with the plate lV and extending` through the door is a sleeve 3 Vwhich is received in an 1 opening,l formed in the plate 2, and surrounding this opelfiingg,` is a collar d formed integral with the plate 2.

Secured to the inner plate lis a. casingl 5 which includes a relatively large portion for the purpose of housing' a` portion of the parts cooperating with the bolt of the lock, and said casing,` also has formed therewith a. portion 6 providedwith apertured ears 7 adapted to receive screws or like securing vreaVns foifiiiing the casing to the door in the manner as illustrated in Figure l. The portion 6 is hollow and is formed with a slot through which is slidably mounted the head 8 of the of die locking` bolt. The head 8 is beveled in the usual manner to provide a cam surface and yias formed therewith a shank 9 slotted as at 10, with a stud 1l extending` in the slot and from the head 8 as best shown in Figure 2.

A band 12 is shaped to follow the shape of the relatively large portion of the casing 5 and this hand surrounds a portion ogt the bolt opeim'ing` means as well as portion ot the permutation means of our loch. The ends et the hand hoffever terminate in spaced relation at the juncture of the portion 6 or" the casing,l and the shank 9 oit the holt is movable between these ends as best shown in Figure 2.

Confined f'ithiu the arca enclosed by the hand is a projection 18 extending outrwardljrY :trom the plate 1 and surrounding said projection 13 is a collar 11i having extending therefrom in alignment with the stud 11 a like stud 15, and these studs 1l and 15 receive a coil spring 1G which is adapted to normally retain the holt in its outer position as shown.

he holt can he operated from either side of the door when it not held against movement, and for this purpose we provide outer and inner plate members 17 and 1S each ot which include housings 19 and 20. These housings have pivotally secured therein latch members Q1 in the form of heli cranl; levers and these latch members have one arm ei;- tendiugj through slots formed in the housings 19 and 2O while the opposite arms thereof have their tree ends disposed in contacting engagement with plates 2Q, mounted :tor slidahle movementloetween guides 23. Each or the plates have termed in their upper ends slots 2i and mounted in one ot these slots is the stud Q5 termed on one end of a bell crank lever' 26 which has a stud on its opposite end tor engagement with the arm 27 of a like shape lerer Q8. The opposite arm' of the hell crank lever is arranged in engagement with a roller 29 mounted 'for rotation on a stud carried by the inner end of the shank S) of the locking bolt as best shown in Figure 2 of' the drawings.

Formed with the plate 1 and passing through the door is a sleeve 30 which has mounted for rotation therein a shaft 31 having` secured to its outer end which as shown in Figure 8 projects into the housing 20, a stud carrying member 32, and the stud of said member is disposed in the slot of the plate arranged in the housing` 20.

m hell crank lever 2G is secured to the end at projects into the casing- 1, s cons ruetion7 it will he apparent e upon either et the latch memi will retract the locking holt. le also revit-e hail handles disposed directly be- ;vn' the housings 19 and 20, so that by gripthe handles. little diiiiculty will be ef;- iced in mo ing the latch n embers with thumb ot the hand gripping the handles.

-au r. o

sition. The plate 36 is operated from the inner side el' the loe t through the instrumen- *t* of a. handle 38 which has a shank passino' through th easing,` and secured to a huti 'y et its center, and to one side 'u `tending` from the opposite *i ecceatricaflljyv arranged with respect to said hu ton is a stud 4L() which is disposed in a slot H11 formed horizontall;7 in said plate 3G. ly this construction, it will he obvious that moif'ement of the handle 38 'will raise and iower the plate 'for positioning` the eX- tcnsion 3T into and out ot the path ot the projection 3d.

rl`he permutation 'feature of the lock operates to prevent n'iovement o1' the holt when the latter is in its operative position as sho vn and includes a stem l2 that is square in cross section and said stem passes through the sleeve 3 and has a portion extending into the collar Li as shown. in Figure 3. T he stem has id to its extending portion numeral heardisk '-3 which has 'formed therein inward- .v of the numerals di a iluralityv of open in; 15 arranojed in circular formation as best shown in Figure 8` and dispose-l hetweer each the immer is which we have shown laing' l to 6 inclusive, an opening 18. These openings act in the same capacity :is the numerals` and exteinling 'from the top oi he collar d n an index pointer which cooperates with the openings and numerals for working t' e t ien structure as will he apparent.

' d to the inner sideoit the stem is a 48 having a coiili;'a1;en edge 'forml and tl'iese recesses are twelve in mnher to correspond to the total number o1" l Fixed to 'he plate 1 through the medium of a screw ias-ein through a strip 5G a springmemher 1 which terminates in a reduced end 52 of a combination oi'v the perniul a Extending outwardly from the disk plateV 48 are pins 53 and formed with said plate 48 is an arm 54 which is disposed at an outward inclination for a portion of itslength and terminates in a straight free end as best shown in Figure 5. Y n

As previously set forth, the recesses 49 correspond in number to the total number oi' the numerals 44 and openings 46, and these ref cesses are disposed in alignment with the numerals 44 and openings 46 with the result the combination can be work-ed by listening to the clicks. When it desired to change the combination :for opening the lock, the casing 5 can be removed and due to the fact that the disk plate 48 is secured to the stem 42 through the medium of a screw as best shown iny Figure 3, this screw can be loosened and the disk plate 48 moved as desired. Then the disk plate has been moved to change the combination, the screwis then tightened up and a new combination has been provided.

Extending inwardly from the casin0l 5 and secured thereto is a headed pin 55 thaving mounted thereon tumblers which are indicated by the reference numerals 56and 57. Each oi the tumblers are formed with recesses 58 and extending from the periphery of one of said tumblers is atongue 59. The tumblers are further provided with lugs 60 which also extend from the peripheries thereof in a manner whereby when these lugs are in contacting engagement, the recesses of one of the tumblers will be disposed out of registration with the recesses of the other. Arranged between the tnmblers 56 and 57 and surrounding the headedpin 55V is a spring washer 6l which normally retains the tumblers in spaced relation as best shown in Figure 3 oi the drawings. Plain washers 62 are secured to the headed pinV and arranged upon the outer sides of the tumblers.

Surrounding the headed pin 55 is a fiat ring member 63 having arranged therein a slot 64 for the purpose of accommodating the free end of the arm 54 which is adapted for rotating the ring member. Formed in the caf-:rin and arrangedtherein-in row formation as shown in dotted lines in Figure 2, are

-may be moved from the inner side of the door for moving the ring member accordingly'.

The disk plate 48 has formed 'in its periph'- be disposed in the 'path of the plate 48 is a finger which prevents movement of the plate 48toward the tumblers for operating the latter-until the recess 69 is disposed in registration with the linger 70 as shown in Figure 4 of the drawings. The disk plate 48 is movable in a direction toward and from the tuinblers through the medium of the stem 42 which is slidably mounted in the sleeve 3. This movement is accomplished by a knob 7l having extending from the inner side thereof a pin 72 adapted to be received in one oi the openings 45 so that the knob which is secured to the outer end of the stem rotates the numeral bearing disk 43 in accordance with the disk plate 48.

Formed with the ring member 63 is an arcuate shape arm 7 3 and this arm extends from the periphery of the ring member and is adapted to be received for slidable movement in a bracket 74A formed with and rising from an obstruction member 75 which is mounted between guide-ways 76 and is primarily de-` signed to'prevent inward movement of the bolt by being disposed in the path thereof when the bolt is vheld against movement by the vpermutation feature of the'lock. It will be apparent that upon rotation of the ring member in one direction, the obstruction member 75 will be lowered'for disposal in the path of the shank 9 andwhen rotated in an opposite vdirection,v it will be raised to the position as shownin Figure 2, through the instrumentality of the arcuate shape arm 73.

The ring member isheld against movement and retained in av position to hold the obstruction member out of the pathy of the shank, by meansV which includes a plate 77 when the handle is rotated, the plate 77 will be moved toward and away tronithe ring member which is provided with a-recessV in its periphery toV accommodate a stud 82 formed with the plate' 77, as best shown in Figure 2 of the drawings.

Wvhen it desired to operate the permuta-A tion feature oi' our lock, the handle 18() must be moved to position for disposing the stud 82 out of the recess 'formed in the periphery oi the ring member, the knob' is then rotated Lfor positioning the first numeral or opening 46 :of the combination in alignment with the index pointer-47, and Vwhen the numeral *or opening is in this posit-ion, the ring of the disk plate 48V will be aligned with the finger 7 so that the diskplate 48 can be'moved toward the tumblers, and further operation of ery a. recess 69 and secured to the plate .l to

the knob to the remaining numerals or openin 46 will move the tumbler 56 through the the tongue 59 thereof, for disposing the recesses o' each of the tumblers in registration With each other for the purpose of allowing the passage ot the pins 53 through the recesses and the arm 5d into the slot Gel whereby the ring member can be rotated in the manner as above set forth.

From the above description and disclosure of the drawings, it will be obvious that We have provided a lock Jfor a door or the like that is ornamental in appearance and can be operated from both sides ot the door when the permutation feature thereof is arranged to its inoperative position, and this feature can be held against operation and the door locked by the other means described.
